NOTES: A. The timer registers are connected to the Memory Bus of the C28x processor.
B. The timing of the timers is synchronized to SYSCLKOUT of the processor clock.

2. CPU-Timer Interrupts Signals and Output Signal (See Notes A and B)
The general operation of the timer is as follows: The 32-bit counter register “TIMH:TIM” is loaded with the value
in the period register “PRDH:PRD”. The counter register, decrements at the SYSCLKOUT rate of the C28x.
When the counter reaches 0, a timer interrupt output signal generates an interrupt pulse. The registers listed
in Table 4
1 are used to configure the timers. For more information, see the
TMS320F28x System Control
and Interrupts Reference Guide
(literature number SPRU078).
